RS-422 is a common transport mechanism for RS-232 extenders. These consist of RS-232 ports on either end of an RS-422 connection. Before hard-disk-based playout and editing systems were used, broadcast automation systems and post-production linear editing facilities used RS-422A [ check spelling ] to remotely control the players/recorders ...
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (e.g. controller) and a slave (e.g. sensor). SSI is based on RS-422 [1] standards and has a high protocol efficiency in addition to its implementation over various hardware platforms, making it very popular among sensor manufacturers.
There is only one Bus Controller at a time on any MIL-STD-1553 bus. It initiates all message communication over the bus. Figure 1 shows 1553 data bus details: operates according to a command list stored in its local memory; commands the various Remote Terminals to send or receive messages; services any requests that it receives from the Remote ...

In the new millennium, RS-422 is slowly phased out in favor of Ethernet for control functions. However its simple way to perform troubleshooting means it will stay around for a long time. In broadcast automation the Video Disk Control Protocol (VDCP) use the 9-Pin Protocol to playout broadcast programming schedules.
Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
While it was originally created for the IEEE-488.1 (GPIB) bus, [5] SCPI can also be used with RS-232, RS-422, RS-485, USB, Ethernet, VXIbus, HiSLIP, etc. [5] SCPI commands are ASCII textual strings, [5] which are sent to the instrument over the physical layer. [5] Commands are a series of one or more keywords, many of which take parameters.
Maximum user data rate, transmission data depending on driver and line of e.g. RS-422: 10 MHz, 1 km; LVDS: 100 Mbit/s Independent of the applied physical layer CRC secured communication (sensor data and control data secured separately) [ 8 ]
